I was hoping that hSetBuffering would turn off the line buffering for stdin, but it doesn't seem to work.---- module Main where import System.IO main :: IO () main = do hSetBuffering stdin NoBuffering hSetBuffering stdout NoBuffering hPutChar stdout '>' c <- hGetChar stdin hPutChar stdout '<' ---- This program should terminate immediately after the first character is typed into the terminal, but it waits until I type a newline. It also looks like it's using GNU readline (it handles the up & down arrow keys.) How do I turn this off and use raw character-based IO? I'm using GHC6.6 on Win32 if that makes a difference.
Using the same platform but I get essentially the same behavior. I too have to type enter to get the program to accept the input, but then it exits immediately so I don't know how you tested the up and down arrows. When I compile this on debian it works as you expected. Perhaps this is a windows bug?
